The Great Roxhythe is set in the glittering but treacherous court of Charles II, in which the brilliant and wealthy Marquis of Roxhythe wears the mask of a cynical, self-serving courtier, allowing even his friends to believe he is cold and disloyal. Yet this public façade is his greatest sacrifice; in secret, he drains his own fortune and stains his own name to operate as the king's most trusted spy and protector. The story is a tragedy of devotion, leaving Roxhythe completely alone, his immense loyalty and suffering a silent burden known only to the sovereign he serves so completely.
